A telephone survey uses a random digit dialing machine to call subjects. The random digit dialing machine is expected to reach a live person 25% of the time. Let X be number of success in ten attempts. What is the probability of achieving at least one successful call? HINT: first find Pr (X=0) and note that Pr (X ≥ 1) = 1 - Pr (X=0) Binomial probability formula: Pr (X=x) = nCx px qn-x where q=1-p 0.944 0.984 0.90 0.844

Assume that a procedure yields a binomial distribution with a trial repeated n=14 times. Use either the binomial probability formula (or a technology like Excel or StatDisk) to find the probability of k=11 successes given the probability p=0.66 of success on a single trial.(Report answer accurate to 4 decimal places.)P(X=k)=

Assume that a procedure yields a binomial distribution with a trial repeated n=6 times. Use either the binomial probability formula (or technology) to find the probability of k=4 successes given the probability of p=0.35  of success on a single trial.(Report answers accurate to 4 decimal places.)P(X=k)=

Assume that a procedure yields a binomial distribution with a trial repeated n=13n=13 times. Use either the binomial probability formula (or technology) to find the probability of k=11k=11 successes given the probability p=0.39p=0.39 of success on a single trial.(Report answer accurate to 3 decimal places.)P(X=11)=

Assume that a procedure yields a binomial distribution with a trial repeated n=7n=7 times. Use either the binomial probability formula (or technology) to find the probability of k=2k=2 successes given the probability p=0.51p=0.51 of success on a single trial.(Report answer accurate to 4 decimal places.)P(X=k)=

Assume that a procedure yields a binomial distribution with a trial repeated n=12n=12 times. Use either the binomial probability formula (or a technology like Excel or StatDisk) to find the probability of k=11k=11 successes given the probability p=0.39p=0.39 of success on a single trial.(Report answer accurate to 4 decimal places.)P(X=k)=

Compute​ P(X) using the binomial probability formula. Then determine whether the normal distribution can be used to estimate this probability. If​ so, approximate​ P(X) using the normal distribution and compare the result with the exact probability. n=51 p=.03 x=20

assume that a procedure yields a binomial distribution with n=4 trials and a probability of success of p=0.30 . use a binomial probability table to find the probability that the number of successes x is exactly 1  p(1)= ?
